Taskman Internals

Taskman components

Routines

•  %ZTLOAD (API to create a task)
• Manager
• Sub-manager
• The menu options to use to manipulate Taskman

Globals

•  %ZTSCH (the tasks "index" plus control structures for taskman... not a Fileman file)
•  %ZTSK (Tasks Fileman file)

^%ZTSK Structure

^%ZTSK contains the actual task.

^%ZTSK(-1) contains the most recently assigned task.

.1 node: Current Status

• 1 -> Scheduled by %ZTLOAD
• 2 -> Not on any list
• L -> Rejected

• 6 -> Succeeded (NB: may not see this if task gets deleted immediately)

.2 node: IO

.3 node: Variables to use in the task
